If it crashes in memtest, it means somebody passed it a wrong pointer or
correct pointer but too large size so that it fell off the cliff.
If there was a bug in memset, you'd notice it far earlier.
So this looks like a quake3 bug.

Quake3 with sound fails with Signal 11 for me with glibc-2.2.4-19 with both the
i386 or i686 versions (this is on an Athlon system). I'm not certain this can be
regarded as strictly a Quake3 bug because using LD_PRELOAD to load a simple
memset() function instead of glibc's causes sound to work. Also, Alan Cox posted
on slashdot that this is probably a glibc optimization bug.
